Comparative Study Between Intravascular Ultrasonography Guided and Angiography-guided Recanalization of Coronary Chronic Total Occlusions

May 17, 2017 updated by: Mohamed Osman Abdelhamead, Assiut University

Randomized Comparative Study Between Intravascular Ultrasonography Guided and Angiography-guided Recanalization of Coronary Chronic Total Occlusions

Chronic total occlusion is defined as thrombolysis in myocardial infarction (TIMI) flow grade 0 with an estimated duration of at least 3 months. The interest in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has increased, but with failure rate up to 20%, leading to important developments in dedicated equipment and techniques.

In the 2014 European Guidelines on Myocardial Revascularization, intravascular ultrasound was recommended to guide stent implantation in selected patients, and this recommendation was a class IIa/level of evidence B.

In CTO PCI, certain angiographic features such as blunt proximal CTO cap, tortuosity, heavy calcification, and lack of visibility of path in the distal vessel increase procedural difficulty

Design Details

  • Primary Purpose: Device Feasibility
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: intravascular ultrasonography guided
Device: intravascular ultrasonography
intravascular ultrasonography will be used during the study for the resolving proximal cap ambiguity of chronic total occlusion, facilitating re-entry into the true lumen after subintimal crossing and confirming distal true lumen guidewire position
Active Comparator: Angiography guided
Device: intravascular ultrasonography
intravascular ultrasonography will be used during the study for the resolving proximal cap ambiguity of chronic total occlusion, facilitating re-entry into the true lumen after subintimal crossing and confirming distal true lumen guidewire position
